The navigation system displays the operating status and instructions for the automatic air conditioning or radio and player,
as well as trip information. Additionally, the navigation system precisely measures the current vehicle position, displays the
map obtained from the map database on the screen, and informs the route to the destination shown on the map using voice
guidance.

6. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off and prolonged braking.
(g) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
7. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1) Install the antenna as far as possible away from the ECU and sensors of the vehicle's electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle's electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3) Do not wind the antenna feeder together with the other wiring as much as possible, also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
8. FOR USING OBD II SCAN TOOL OR TOYOTA HAND-HELD TESTER
CAUTION:
Observe the following items for safety reasons:
Before using the OBD II scan tool or TOYOTA hand-held tester, the OBD II scan tool's instruc-
tion book or TOYOTA hand-held tester's operator manual should be read thoroughly.
Be sure to route all cables securely when driving with the OBD II scan tool or TOYOTA hand-
held tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel
and shift lever.)
Two persons are required when test driving with the OBD II scan tool or TOYOTA hand-held
tester, one person to drive the vehicle and the other person to operate the OBD II scan tool or
TOYOTA hand-held tester.
